Exwith a loop 20 adapted to be grasped by the Patented Nov. 5, 1929 UNITED STATES PATENT OFFICE Application filed October 6, 1925; Serial No. 60,791.

The invention relates to graders, particutending downward1y from the beam 1 adlarly of the typeshown in Patent No. 1,510, jacent its forward end is an arm 5 which 958, issued to William B. Quillen, October terminates in a horizontally disposed portion 7th, 1924, and has for its object to providea 6, adapted to slide over the ground forwardly 5 U-shaped bracket through which the arcuate of the scraping blade 4 for supporting the 51 member carried by the pivoted scraper blade forward end of the beam 1 at a substantial moves, and which U-shaped bracket is pro uniform distance from the ground during the vided with arms engaging the upper side of scraping operation of the blade 4. It will be the scraper beam, and held in close engagenoted the blade 4 can be moved to various U-shaped bolts, the arms of which extend ing the dirt collected thereby to either side through plates disposed on the upper side of of the grader during the scraping operation. the bracket arms, thereby positively holding Blade 4 is provided with a substantially the bracket in place on the upper side of the horizontally disposed segmentally shaped Afurther object is to provide a sliding bolt tures 8 therein, and with which guide bar extending through an upwardly extending latching means cooperates for holding the arm of one of the arms of the bracket and scraper blade in various adjusted positions throughregisteringapertures in the U-shaped in a horizontal plane. The bar 7 is disposed shaped member, and which latching bolt is material during a scraping operation.

maintained in operative position by means The latching device comprises a Ushaped of a coiled spring. The latching bolt forms bracket 9 above the beam 1, the arms 10 of means for allowing the grader blade to be which extend downwardly and terminate in sition, and held in adjusted position. engage the upper side of the beam 1, and are A further object is to dispose the latching held in close binding engagement with the device and the apertured segmentally shaped beam 1 by means of U-bolts 12, which arch member above the beam where they will not the underside of the beam and extend through *30 come into engagement with, dirt, vines or the plates 13 and 14 disposed on the upper 30 other material during a scraping operation. sides of the arms 11, and one of which plates With the above and other objects in View has secured thereto the handle members 14 the invention resides in the combination and and the brace rods 15,therefore it will be arrangement of parts as hereinafter set forth, seen that it is not necessary to drill the beam shown in the drawing, described and claimed, 1, and the handle members and braces may 5 it being understood that changes in the prebe assembled on the plate 14 and placedin cise embodiment of the invention may be position and the U-shaped bolts 12 placed made within the scope of what is claimed under the beam 1 and through the apertures without departing from the spirit of the in- 15 of the plates 13' and 14, and the handles In the drawing by means of the bolts. It will also be seen Figure 1 is a top plan View of the grader. that the U-shaped bolt 12 at the forward end Figure 2 is a side elevation of the grader. of the plate forms means for securing the Figure 3 is a perspective view of the latchbrace rods 15 to the plate 14, therefore they Referring to the drawing, the numeral 1 one of the arms 11 is provided with an updesignates the beam of the grader, the rear wardly extending arm 16, and in which arm, end of which is provided with a downwardly and the arms 10 a slidable latch bolt 19 is extending arm 2, to which is pivotally conmounted, the outer end of which is provided operator for moving the sliding bolt 19 outwardly against the action of the coiled spring 21 which is interposed between the arm 16 and the pin 22 of the bolt, when it is desired to adjust the blade 4 to a different position. The sliding bolt 19 extends through registering apertures 23 of the arms 10 of the bracket and through one of the apertures 8 in the segmentally shaped guide bar 7 and when in locked position positively holds the scraping blade 4 against pivotalmovement during the scraping operation. I

From the above it will be seen that a positive latching device is provided for a segmentally shaped brace bar of a grader blade, which latching device is provided in connection therewith with a ii shaped guide bracket for the brace bar, and the same securing bolts which hold the latching device also holds the handle carrying plate disposed on the upper side of the beam, and the beam is not weakened by drilling holes for the bolts. It will be seen also that the segmentally shaped bar 7 and the latching device are disposed above the beam 1 and scraper 4: therefore they will not come into engagement with material being scraped by the blade i.

The inventionhaving been set forth what is claimed as new and useful is l. A grader comprising a beam, a pivoted blade carried thereby, a segmen ally shaped apertured guide and brace bar carried by said blade and disposed above the beam, a latchingdevice for said brace bar, said device comprising a U-shaped bracket above the beam through which the segmentally shaped brace bar extends, outwardly extending arms carried by the U-shaped bracket and engaging the upper side of the-beam, U-bolts arching the under side of the beam for holding said arms in close binding engagement with the upper side of the beam, transversely disposed plates engaging the upper sides of the bracket arms and through which the bolts extend, one of said arms being provided with an upwardly extending member spaced from the U- shaped bracket and disposed in a recess in one of the plates, a sliding bolt extending through the upwardly extending member and registering apertures in the U-shaped bracket, a

stop carried by said sliding boltand a coiled 7 spring surrounding the sliding bolt and interposed betweenthe stop and the upwardly extending member.

2. A grader comprising a beam, a pivoted scraper carried by said beam, a segmentally shaped apertured brace bar carried by said scraper and disposed above thebeam, a bracket engaging the upper side of the beam, latching means carried by said bracket and cooperating with the brace member for holding the same in various adjusted positions,a plate disposed on the upper side of the bracket, handle members carried by said plate and entirely supported thereby, brace rods connecting said WILLIAM B. QUILLEN.
